Cleveland Twist Drill Q Series Drills

Cleveland Twist Drill's Q Series drills are designed
to operate at penetration rates up to 5 times that of conventional
high speed twist drills in carbon steel, alloyed steel and stainless
steel. This is made possible through a combination of a unique
flute
shape together with controlled point geometry, which
promotes exact chip formation and subsequent chip breakage.

The Q Series' tighter hole size control, within
.0015", enables the elimination of most reaming operations.

The controlled point geometry of the Q Series
drill is reproducable on conventional pointing/notching equipment.
Unlike other high penetration rate drills, the additional expense
of dedicated regrinding equipment or limited regrinding services
is not needed.
